I often buy Chinese tea by weight in some local stores and at times I find some inclusions that should not be there. Up to this date I have found:
- A human hair
- Some sand
- Some white dots (presumably parts of a plant) that always come with Pu'er stones and float on the surface
- Parts of other plants or a trunk parts of the tea plant that was not meant for tea
- Some kind of fluff (https://biology.stackexchange.com/questions/74851/identify-fluff-that-i-have-found-in-tea)
Finding the fluff finally got me and I decided to ask here.
Is it normal for tea to contain various inclusions like that? I understand that tea processing is a complex process performed by humans at factories in huge batches. So is it common for something like that to get into the process?
I ask because, for example, if you consider some kind of grain, there are often inclusions of other things (other grains or something else) too, and this is known and normal for lower quality (cheaper) grain. You don't throw away the pack if there are some other kind of grains and you simply remove them. Various manufacturers differ in quality and you can choose. You know that the more expensive grain should be better processed and have no inclusions, when a cheaper one is ok to have them. Now this is not the case with the Chinese tea. There's no (obvious) choice of the manufacturer, it simply comes from a particular part of China. I can only choose a local vendor and which tea grade to buy (where tea grade tells what part of the tea plant was used in the making, and nothing more, not the quality of the manufacturing).
I have started drinking Chinese tea not so long ago, and I don't have much experience of it. So my question is: are the inclusions that I have described above common and known for tea, or should I consider buying at a different store, from a different vendor? If the tea is coming from China, will it be different, or is it the same in all the shops? What would you do in a situation like this?
